Introduction

The addition of MRI fusion guided prostate biopsy (FusionBx) to transrectal ultrasound guided template biopsy (TRUSBx) has emerged in urology due to its increased sensitivity in detecting clinically relevant prostate cancer (PCa) over TRUSBx alone. FusionBx in conjunction with TRUSBx requires more biopsies in less accessible locations and takes more time than TRUSBx, suggesting that FusionBx+TRUSBx may be less tolerable to patients than TRUSBx alone. The objective of our study was to investigate patient pain associated with FusionBx+TRUSBx versus TRUSBx, which has never been studied before.

Methods

Patients undergoing FusionBx+TRUSBx or TRUSBx alone from April through September 2016 at Columbia University Medical Center for PCa detection or surveillance were asked to complete a validated pain survey immediately after biopsy. Responses were graded from 0-10 (0: no pain/willing to return for repeat procedure; 10: excruciating pain/not willing to return for repeat procedure). Procedures were performed by a single urologist with a 1% Lidocaine periprostatic nerve block. Pain scores between groups were compared via Mann-Whitney U test.

Results

A total of 94 patients were included, with 50 FusionBx+TRUSBx and 44 TRUSBx. For each group, median age was 66.5 (range 47-84) and 68 years (range 44-86), and median number of cores was 14 (range 12-22) and 12 (range 6-14), respectively. Prostate biopsy pain questionnaire scores did not differ significantly for any of the questions (Figure 1). Patients in both groups had mild discomfort overall with the procedure (3 out of 10), the probe insertion (2 out of 10) and the biopsy portion of the exam (3 out of 10). If medically necessary, both groups were very willing to come back for the same procedure again (1 out of 10).

Conclusions

Patients reported no difference in pain or discomfort with added FusionBx relative to TRUSBx alone. Both procedures were mildly painful with patients very willing to return for repeat biopsy if necessary. Patients tolerate the addition of FusionBx to TRUSBx alone. Patients&[prime] pain experience or discomfort does not seem to hinder whether FusionBx of the prostate should be performed, or not.
